Arduino library for signal filtering

Overview

This project is a free initiative to create an Arduino library for signal filtering.

• Some information about the filters
• Free ebook: "The Scientist and Engineer's Guide to Digital Signal Processing" http://www.dspguide.com/

Available filters:

• low pass filter (1st and 2nd order, Chebychev and Bessel)
• median filter

Library Usage

• Download the source
• Place the Filter folder in your Arduino1.0+ "libraries" folder
• Open example sketch: "file", "Examples", "!SignalFilter", "Bessel" (or any other example)
• Connect a (noisy) analog sensor to port A0
• Compile & upload code
• Original and filtered sensor data should be arriving over the serial port

Version History:

• Version 0.1: Low pass Chebychev and Bessel filters
• Version 0.2: Median filter

Roadmap:

• Version 0.3+: More filters (band pass, running average, Kalman, ...)
